Journal ArticleDOI
Assessment of heme oxygenase-1 (HO-1) activity in the cavernous tissues of sildenafil citrate-treated rats
M. Talaat Abdel Aziz,M. Farid Al-Asmar,Taymour Mostafa,Hazem Atta,Laila A. Rashed,Dina Sabry,Shedeed Ashour,Ahmed T. Abdel Aziz +7 more
TL;DR: The actions of PDE5 inhibitor sildenafil citrate in the cavernous tissue are partly mediated through the interdependent relationship between both HO-1 and NOS activities.
Journal Article
Amelioration of Murine Schistosoma mansoni Induced Liver Fibrosis by Mesenchymal Stem Cells.
Abdel Aziz M,Hazem Atta,Nagwa K. Roshdy,L. Rashed,Dina Sabry,Amira Hassouna,Aboul Fotouh G,N.M. Hasan,Younis R,Chowdhury J +9 more
TL;DR: The hypothesis that MSCs participate in liver regeneration and functional improvement by reducing liver fibrosis is supported, probably by modulating the relative expression of MMP and TIMP.
Journal ArticleDOI
Retrovirus-mediated human heme oxygenase-1 (HO-1) gene transfer into rat endothelial cells: the effect of HO-1 inducers on the expression of cytokines.
Mohamed T. Abdel-Aziz,M.F. El-Asmar,Dawlat El-Miligy,Hazem Atta,Olfat G. Shaker,Maivel H. Ghattas,H. Hosni,Nagwa Kamal +7 more
TL;DR: Investigation if the mechanism of human heme oxygenase-1 (HO-1) mediated angiogenesis was through the induction of vascular endothelial growth factor (VEGF) and the effect of HO-1 on the expression of transforming growth factor beta (TGF-beta) was studied in the presence and absence of HO inducers.
Journal ArticleDOI
Human Umbilical Cord Stem Cell Xenografts Improve Cognitive Decline and Reduce the Amyloid Burden in a Mouse Model of Alzheimer's Disease
TL;DR: Human umbilical cord mesenchymal stem cells appear to reduce AD pathology in a transgenic mouse model as documented by a reduction of the amyloid plaque burden compared to controls.
Journal ArticleDOI
Effects of Losartan, HO‐1 Inducers or HO‐1 Inhibitors on Erectile Signaling in Diabetic Rats
Mohamed T. Abdel Aziz,Mohamed Farid El Asmer,Taymour Mostafa,Hazem Atta,Soheir Mahfouz,Hanan Fouad,Laila A. Rashed,Dina Sabry,Amira Hassouna,Ahmed T. Abdel Aziz,Amira M. Senbel,Ahmed B. Demery +11 more
TL;DR: The decline in erectile function in diabetes mellitus could be attributed to the downregulation ofHO-1 gene expression and HO-1 induction added to Ang II receptor antagonist could improve erectilefunction.
